Study Notes

Crayfish Internal Anatomy

Green Gland: Responsible for waste excretion through pores located at the base of the antennae.
Antennule: The shorter antenna used for sensing environmental stimuli.
Antennae: The longer type of antenna that aids in sensing the environment.
Excretory Pores: Openings that allow waste to exit from the green glands.
Rostrum: A bony protective structure located between the eyes of the crayfish, providing defense for the head.
Brain: Central control unit enabling the crayfish to perform various functions.
Mouth: Entry point for food, allowing the crayfish to consume its diet.
Esophagus: The tube that transports food from the mouth to the stomach.
Cardiac Stomach: A type of stomach in crayfish that holds and begins the digestion of food.
Ostia: Valve openings in the heart wall that facilitate circulation.
Heart: Central organ of the circulatory system, vital for pumping blood.
Digestive Gland: Organ involved in food digestion and sending nutrients through the intestine.
Abdominal Gland: A cluster of nerves located in the abdomen that plays a role in the nervous system.
Intestine: Organ responsible for controlling waste excretion in the crayfish.
Ventral Nerve Cord: The central nerve running along the underside of the crayfish's body, part of its nervous system.
Dorsal Abdominal Artery: Main artery extending from the heart, supplying blood to the body.
Telson: The strongest and most posterior part of the crayfish's tail, aiding in propulsion.
Anus: The exit for waste, important for the digestive process.
Uropod: Appendage that assists in swimming by providing maneuverability.
Swimmerets: A series of small appendages that also aid in swimming and can serve reproductive functions.
First Pair of Swimmerets: Specifically tailored to assist with swimming, providing stability and movement.
Vas Deferens: Tubes that are essential for the reproductive process in male crayfish.
